When using the NRIV rename, duplicates may occur.

not sufficiently specified.

How to fix this error?

Possible solutions:
Either
1.) the NRIV rename for the respective object is set to 'inactive' in
the the following IMG step, and (if necessary) a prefix rule for this
object is defined

addded in table NRIV, and then the iIMG step 'Determine
conversion-relevant number ranges' must be repeated.
